Hire a DevOps engineer who can tell you their rollback time
To hire a DevOps engineer, first decide whether you need pipelines, infrastructure as code or on-call reliability, because one title covers all 3. Source from people running Kubernetes, Terraform and CI in production, and test failure handling. O*NET files DevOps under software developers, whose May 2025 BLS median was $135,980.
DevOps, SRE or platform engineer: which one are you hiring?
Companies use these titles loosely. Write down what the person owns in the first 6 months, then pick the title that the market uses for that work.
| If they mainly own | Market title | Judge them on |
|---|---|---|
| Build, test and deploy pipelines; release safety | DevOps engineer, build and release engineer | Pipeline design, rollback speed, developer wait time |
| Uptime, SLOs, on-call and incident response | Site reliability engineer | Incidents worked, alert quality, error budgets |
| Internal tooling and paved paths for other teams | Platform engineer | Adoption by other teams, self-service, golden paths |
| Cloud accounts, networking, Terraform and cost | Cloud or infrastructure engineer | Infrastructure as code, drift, spend |
Most DevOps job ads mix 2 of these rows. Rank them, or the interview will test the wrong thing.
Where to find DevOps engineers
In production, mostly at companies that already went through the migration you are planning. Search for the toolchain together with the scale: Kubernetes plus a cloud provider plus a CI system, and a sign they ran it for real users. Public traces help: contributors to CNCF projects, module authors on the Terraform Registry, and speakers at KubeCon and SREcon.
Systems administrators are an underused pool. BLS projects sysadmin employment to fall 4 percent from 2025 to 2035, and many admins have spent years automating their own work in Ansible, Bash and Terraform. For a pipeline-heavy role, someone like that can be a strong hire with a short ramp.
Search strings for a DevOps engineer
Pair every tool with a production signal. "Kubernetes" on its own returns everyone who finished a course.
BOOLEAN
("DevOps engineer" OR "site reliability engineer" OR SRE OR "platform engineer" OR "infrastructure engineer")
AND (Kubernetes OR EKS OR GKE)
AND Terraform AND ("GitHub Actions" OR GitLab OR Jenkins OR ArgoCD)
AND ("on-call" OR incident OR production OR SLO)
NOT (intern OR trainee OR recruiter)
GITHUB X-RAY
site:github.com "terraform" "module" "eks" "helm"
PLAIN-ENGLISH BRIEF
DevOps engineer, 4+ years, who has run Kubernetes on AWS in production with Terraform and GitHub Actions or ArgoCD, owned a deployment pipeline with automatic rollback and has been on call. Remote, US Eastern or Central.
Matches judged against your must-haves
Every card opens with a "Why this match" line, such as the current role or a listed skill.
The Cognitive reads the brief above into editable filters and searches ~900M public profiles. Anyone who misses a must-have, say production Kubernetes, drops below the people who meet it; nobody is removed. Tenure per role and an "Open to work" badge show who might move now.
What does a DevOps engineer cost in 2026?
BLS publishes no DevOps line. O*NET lists "DevOps Engineer" as a reported title under software developers, so that is the closest federal benchmark.
| Measure | Software developers (DevOps sits here) | Systems administrators |
|---|---|---|
| Median pay | $135,980 a year (May 2025) | $99,130 a year (2025) |
| Outlook, 2025 to 2035 | 10 percent growth for the group | 4 percent decline |
| Openings per year | About 106,100 for the group | About 13,400 |
| What it tells you | Price the role as engineering, not operations | A pool moving toward automation work |

What to assess in a DevOps engineer, with example questions
DevOps depth shows when things fail. Every card below asks about a failure the candidate personally handled.
Walk me through a deployment pipeline you built or rebuilt. What did it look like before and after?
Build caching, test stages and a canary in GitHub Actions, GitLab CI or Jenkins, with an automatic rollback when the canary failed.
When a bad release got through, what stopped it, and how long did the rollback take?
How did you structure Terraform for more than one environment?
Modules and remote state, and what they did about drift or a plan that wanted to replace a production database.
Tell me about a pod that would not stay up.
Debugging CrashLoopBackOff with kubectl describe and logs, and the resource limit or readiness probe that turned out to be wrong.
What is the biggest cloud saving you made, and where did your secrets live?
A concrete saving, such as rightsizing EC2 or moving CI runners to spot capacity, and secrets moved from env files into Vault or AWS Secrets Manager.
Describe an outage you worked. What was the first signal?
The first alert, the mitigation they chose under pressure and the follow-up item they personally owned afterwards.
What did you change so the same alert would fire earlier?
Engineers who actually ran the pipeline can quote the rollback time. People who only automated the happy path describe the stages.
A DevOps engineer hiring process in 5 steps
Engineers with production Kubernetes and Terraform get a lot of messages. Plan a loop that finishes inside 2 weeks of the first interview.
- Rank the 4 scopes Use the table at the top. Write the first 6 months of work and the on-call expectation in hours per month.
- Source by toolchain plus production Search the titles together, read for a production signal, and include systems administrators who automated their own work.
- Structured first interview Cover pipelines, infrastructure as code, Kubernetes, cost and incidents on one scorecard, each anchored in a failure they handled.
- Incident or design exercise with your team Walk a real past incident from your system, redacted, and ask what they would check first. Score it alone before the debrief. "Deploys started failing at 14:02. Here are the first 3 alerts. Where do you look?"
- Close fast Agree the on-call rota and the offer in one conversation. Strong DevOps candidates rarely wait for a slow process.
How The Cognitive fits a DevOps hire
A live, two-way AI video interview of 10 or 20 minutes, at a slot the candidate books.
Invite the engineers you sourced to a live AI video interview. The rubric is fixed for the role and each question follows from the last answer. The report scores every criterion 1 to 5, adds overall written feedback and includes the transcript and recording.
Screening DevOps engineers: do and don't
Do
- Ask for numbers: rollback time, deploy frequency, monthly cloud spend they managed
- Treat certifications such as CKA or AWS as tie-breakers
- Say the on-call load in the first message
- Include sysadmins who automated their own work
Do not
- Make a certification a must-have; it shrinks the pool and proves little
- List every tool you might ever use as required
- Hire an SRE when you need pipelines, or the reverse
- Run 5 rounds for a role the market fills quickly

Frequently asked questions
How much does it cost to hire a DevOps engineer?
BLS has no DevOps code, but O*NET lists DevOps Engineer under software developers, whose May 2025 median was $135,980 a year. Systems administrators had a 2025 median of $99,130, which is why pricing a DevOps role as operations tends to lose candidates. Add sourcing, interview time and any agency fee on top.
Where do I find DevOps engineers?
Search profiles for people running Kubernetes, Terraform and CI in production, then add CNCF contributors, Terraform module authors, KubeCon and SREcon speakers and systems administrators moving into automation. The Cognitive searches ~900M public profiles from a plain-English brief and shows tenure per role and an "Open to work" badge on each person.
What is the difference between DevOps and SRE?
In most job ads, a DevOps engineer owns how code gets built and deployed, and a site reliability engineer owns how it behaves once it is running: SLOs, alerts and incidents. Many roles mix both. Rank which matters more before you search, because the interview should test the one you need.
How long does it take to hire a DevOps engineer?
There is no reliable public time-to-fill figure for DevOps specifically. The usual delays are a vague scope, a long list of required tools and too many rounds. Scope the role first, source from day 1 and keep the loop to 4 stages.
Should I require DevOps certifications?
Usually not. A CKA or an AWS certification shows someone studied; a rollback time and an incident story show they ran it. Use certifications to break ties, and make them a must-have only if a customer contract requires them.
Can an AI interview screen DevOps engineers?
Yes, for reasoning and experience. The Cognitive runs a live, two-way AI video interview that asks about pipelines, infrastructure and incidents, adapts to each answer and checks up to 5 resume claims. It does not run hands-on labs, so keep an incident exercise with your own team.
What does The Cognitive cost?
AI Sourcing and AI Interview each start at $99/month. Plans are billed monthly and you can cancel anytime. Interview plans include a monthly interview allowance, and interviews beyond it come from a top-up.
